# The distance d in miles that a car travels in t hours at a rate of 58 miles per hour is given by the equation d=58t. What is the best estimate of how far a car travels in 7 hours?

The car travels $\textcolor{b l u e}{406}$ miles in 7 hours.

#### Explanation:

We are already given an equation, with $\textcolor{b l u e}{d}$ meaning distance (miles) and $\textcolor{red}{t}$ meaning hours (time).

$\textcolor{b l u e}{d} = 58 \textcolor{red}{t}$

Now we can plug in $\textcolor{red}{7}$ for $\textcolor{red}{t}$ since it is a hour value.

$\textcolor{b l u e}{d} = 58 \left(\textcolor{red}{7}\right)$

Now simplify to find the desired distance.

$\textcolor{b l u e}{d} = \textcolor{b l u e}{406}$
